3.9.3-3 Installation failing

Hi Team,
I am trying to install TGDB 3.9.3-3 on Oracle Linux 7. And the installation is getting terminated and losing access to nodes(got to reboot node)

$ sudo ./install.sh -n
[sudo] password for tigergraph:

Welcome to the TigerGraph platform installer!

[NOTE    ]: You are using OEL system: Please follow the following steps before installation:
      If you want to use new user for tigergraph, for each node, create an OS user and password:
        sudo useradd NEW-USER
        sudo passwd NEW-USER
      Then add the new user to AllowUsers row in /etc/ssh/sshd_config file, for example, the row
      will look like:
        AllowUsers OLD-USER NEW-USER
      Then restart sshd by
        /sbin/service sshd restart
      Firewall rules will be added to allow tcp communication between nodes in the cluster.

[NOTE    ]: The installer will make the following changes to system:
(it is recommended to accept the changes, but the installation will continue if they are rejected.)
1. Set NTP system time synchronization, do you accept?
(If rejected, it is user's responsiblity to synchronize the system time among cluster nodes) (y/N): Reject
2. Set iptables (firewall) rules among cluster nodes, do you accept?
(If rejected, it is user's responsiblity to make tcp ports open among cluster nodes) (y/N): Reject

Network error: Software caused connection abort

I also noticed, that below two options are being auto selected to “reject”

[NOTE    ]: The installer will make the following changes to system:

1. Set NTP system time synchronization, do you accept?

Any thoughts on this issue.
